I doubt the stack_setup() was defective before:
we load the current location of _start and compare against destination
of relocate_code(). If we are already there we shoud skip the
relocation and jump over to clear_bss. Before the clear_bss was also skipped.

Dear Albert,
(or whoever works with armv7 currently)
However I doubt there is another issue when CONFIG_PRELOADER is not set!
Then the bss will never be setup, is that correct?
